Physicist Bends Light Waves On Surfboards, Next Are Invisibility Cloaks
A physicist has successfully combined physics and his passion for surfing to build a new technology that has inspired many. Dr Matt Lockyear, a student at Exeter University has used foam from inside of Surfboards and made materials that could manipulate light. Dr. Lockyear has always been found interested in metamaterials apart from stealth materials, light weight ultra thin radar absorbers, beam steering, smart antennas, and such. The metamaterials include specifically engineered 'pseudo atoms' that provide properties to materials that not natural in nature.

In his recent work, he has included his passion for surfing and physics to build a 'Surface Wave Black Hole'. He chose the surfboard foam as his material, the material that had to be uniformly dense and that responded the same as air to electromagnetic radiations. The radiations that propagate through the metamaterial had to pass thorough a radially graded indexed material placed over it - slower the radiation, higher is the index. The radiations propagating through these materials gets refracted and absorbed to the core spirally, bending the light.
Like many scientists across the globe, Dr. Lockyear has now started working on creating the Harry Potter-like Invisibility Cloaks. This would require building the properties in the material that will guide light around the object making it invisible.
